A Study on the Selection of Expansion-Causing Substances for the Use of Converter Slag as Aggregate for Concrete
전로슬래그의 콘크리트용 골재로서 활용을 위한 팽창유발 물질 선별 연구
Abstract
The use of converter slag as an aggregate for concrete is limited due to the risk of expansion. This study analyzed the substances causing the expansion of converter slag and evaluated the possibility of its use as an aggregate for concrete through separation and selection. As a result of the experiment, it was confirmed that CaO and MgO were concentrated in the slag particles inducing expansion, and it was confirmed that it was possible to separate them from non-expanded particles through magnetic.
